ABSTRACT
People involved in programming, designing and evaluating buildings are in gen-
eral concerned to achieve the best possible quality in the circumstances,
subject to limiting conditions such as time, money, legislation and regulations.
It is therefore essential to be clear what quality means, what level of quality is
wanted and how this level can be translated into spatial performance require-
ments and design solutions. This chapter presents a number of criteria for
developing and testing plans (programme of requirements, structural design,
provisional design and definitive design) and realised buildings, with the empha-
sis on functional quality.
